Tumbling Brass for Fun and Profit

One of the nice things about being in the lab all day is that my apartment is unoccupied. That, combined with the good soundproofing between units means that I can run my tumbler all day without me or my neighbors going crazy from the droning sound.
Due to this fortuitous situation, I’ve been tumbling all my spent brass, both once-fired stuff I’ve shot but also stuff I’ve harvested from the range. I’ve still got a bunch left, but it’s going at a pretty good pace.
I’ll probably run out of brass to tumble in the next few weeks, and so I wanted to extend an offer to my readers: if you mail me your brass in bulk ((Preferably in the same caliber, or at least the same neck diameter — this prevents cases from “nesting.”)), I’ll tumble it to a high shine (( ~7 hours in crushed walnut shells treated with Flitz tumbler additive. )) and send it back. You need only pay for shipping both ways (( Whatever’s cheapest works fine. If you’re in the Tucson or Chandler areas, no shipping is needed.)) and make a small donation to the New Shooter Ammo Fund, say $20/1,000 pieces of brass with a 250 piece minimum.
For a slight additional donation (to be negotiated), I can deprime your boxer-primed cases.
You’ll get your own cases back — I don’t do “case exchange” processing.
Due to size and capacity limitations of my tumbler and press, I can’t accept very large cases like 20mm, .50 BMG, and so forth. Basically, I’ll take anything that can fit in the Lee Universal Depriming Die.
Tumbler time will be allocated on a first-come, first-served basis, and is dependent on the number and size of cases. Large numbers of big cases will take longer to process than smaller numbers of smaller cases, obviously.
Any money collected will go to the New Shooter Ammo Fund for the purpose of buying ammo for teaching of and use by new shooters, rather than for my own personal use. Donations to the fund are not tax-deductible.
